The leaders of Turkey, Iran and Russia are meeting to try to advance peace efforts in Syria`s northwest, following attacks by Syrian government forces that risk deepening regional turmoil and pushing a new wave of migrants towards Turkey.

Trump said on Monday he would meet Iran`s president under the right circumstances to end a confrontation over Tehran`s 2015 nuclear deal with six powers and that talks were underway to see how countries could open credit lines to keep Iran`s economy afloat.

Tensions have risen between Iran and the West since 2018 when the United States pulled out of an international agreement which curbed the Islamic Republic’s nuclear programme in return for an easing of economic sanctions on Iran.

European signatories have not done enough to preserve the landmark 2015 nuclear deal and it would be in the benefit of European countries and the US to stick to their promises under the deal, Rouhani said.

President Hassan Rouhani rejected Zarif’s resignation last Wednesday, bolstering a moderate ally who has long been targeted by hardliners in factional struggles over the 2015 nuclear deal with the West.
